Available SARS-CoV-2 Variants

Thirty SARS-Related Coronavirus 2 (SARS-CoV-2) isolates are now available from BEI Resources, including isolates classified as Variants of Concern and Variants of Interest.1 Isolates originated from the United States (Washington, Arizona, Wisconsin, Illinois, California and New York) and internationally (Brazil, Canada, Chile, England, Germany, Hong Kong, Italy, Japan, Scotland, South Africa and Singapore). The available and upcoming isolates represent lineages B.1.1.7, B.1.351, P.1, B.1.5, B.1.1.298, B.1.222, B.1.526, B.1.617, R.1 and B.1.1.1 (also known as C.37).

SARS-CoV-2 isolates are produced in vitro by infection of Cercopithecus aethiops kidney epithelial (Vero) cells or Homo sapiens lung adenocarcinoma (Calu-3; ATCC® HTB-55™) cells with the deposited material and are provided frozen as spin-clarified cell lysate and supernatant. All SARS-CoV-2 isolates have been analyzed by Next Generation Sequencing with respect to the SARS-CoV-2, Wuhan-Hu-1 strain. Observed sequence variations and detailed lot-specific data such as passage history and titer are available on the Certificate of Analysis for each item.

BEI Resources is working hard to accession and authenticate SARS-CoV-2 isolates as they become available. Requests continue to be fast-tracked and prioritized, with an anticipated turnaround window of 12-to-72 hours for new SARS-CoV-2 registrations and 24-to-48 hours for shipments of new orders. For more information on the ordering process and how to register, please refer to our Frequently Answered Questions or contact Customer Care at contact@beiresources.org.
